Secure Cloud Storage and Communication. Privacy by design.

MEGA is a secure, user-controlled end-to-end encrypted cloud storage and communications service with 20 GB free storage space. Unlike other cloud storage providers, your data is encrypted and decrypted by your client devices only and never by us.

This extension allows you to install MEGA into your browser to reduce loading times, improve download performance and strengthen security. Any MEGA URL will be captured by this extension and stay local (no JavaScript will be loaded from our servers).

MEGA’s source code files (HTML, CSS and JavaScript) are loaded from the extension itself and do not require additional integrity verification. This saves time by not downloading these files from MEGA’s servers and verifying them each time you visit the MEGA website. The executable client code runs directly on users' local machines, rather than being loaded from MEGA over TLS/SSL. Browser extension updates are cryptographically protected. For more information see section 2.2 of our whitepaper

Risk impact

MEGA requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install MEGA if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

MEGA is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.
